Abstract
In the image processing apparatus, Input transform into an input color space is performed on input image data; After the input transform, transform processing of transforming chroma or chromaticity of the input image data or chroma or chromaticity in the input color space is performed so as to reduce a difference between a space of chroma or chromaticity of the input image data and a space of chroma or chromaticity in the input color space to acquire transformed image data; and Output transform into an output color space is performed on the transformed image data using a three-dimensional lookup table including inverse transform processing of returning the chroma or chromaticity of the transformed image data to the chroma or chromaticity of the input image data to acquire output image data.
